Modeling of synthetic aperture radar for nonconventional geometry

Basic SAR equations for Doppler bandwidth, point-scatterer response, focused and unfocused resolution, and iso-Doppler contours, are presently generalized to the case where the platform is not in level flight and the radar is squinted. The effects of the geometry on S/N, minimum pulse repetition frequency, and maximum swath, are also noted. A computer simulation of a mm-wave SAR on a translating and rotating missile platform is employed, and selected plots of the detailed geometric behavior of several key SAR quantities ae presented.
